城镇是非农产业的集聚地。通过应用克鲁格曼G指数来考察2005—2013年中国制造业中29个子行业、服务业中14个行业门类的省际布局变迁情况。研究表明,与制造业相比,服务业集聚水平较低。2005—2013年间,大部分制造业子行业均经历了集聚、转移扩散、再集聚这一全周期过程,其中劳动力密集型产业相对于原材料密集型产业和资本密集型产业更早地呈现出了转移扩散的特征。服务业同样表现出转移扩散的新趋势,但是转移扩散的时间略微滞后,且只有少数几个行业表现出再集聚特征。最后,研究指出地方政府在承接产业转移的过程中需尊重客观规律,大力承接率先转移出来的制造业产业,并为未来服务业(尤其是生产性服务业)的迁入做好充足准备。
Non-agricultural industries always cluster in urban area. The article analyses the distribution of non-agricultural industries from 2005 to 2013 using Krugman G index. The article indicates that compared with the manufacturing industry, agglomeration level of service industry is relatively low. Most of the manufacturing sub-sectors have experienced agglomeration, then dispersion, and then agglomeration again. With respect to raw material-intensive industries and capital-intensive industries, the labor-intensive industries relocate earlier. The service industry also shows a new trend of dispersion, but it has a lag in the time characteristics. In the process of industrial transfer, the local government should undertake the transfer of manufacturing industry firstly and prepare for the transfer of service industry in the future.
